Article Preview

Bio-ferric membrane bioreactor(MBR) was made through adding ferric hydroxide to traditional MBR and forming bio-ferric sludge. Through analyzing treatment efficiency of dyeing and printing wastewater in bio-ferric MBR and traditional MBR respectively, the results showed: COD removal efficiency in bio-ferric MBR was more better than that in traditional MBR which increased 10% or so, but the influence of HRT on COD removal efficiency wasn’t evident; Via changing SRT, it was obtained: bio-ferric MBR could operate in longer SRT while treatment effect couldn’t be impacted that could discharge less sludge than traditional MBR which coule get sludge minimization; bio-ferric sludge flocs could provide better survival environment for nitrobacteria that made NH3-N removal efficiency stable. The experiment illuminated: the biochemical and physical function of bio-ferric sludge could strengthen the holistic stability of the system.
